Echidnas and brush-tailed bettongs live in this yard. The wombat is next door. Sugar gliders supposedly live in the trees, but I did not see any.
As of spring 2015 this is the only major nocturnal exhibit in California as the SF Zoo's aye-aye exhibit has closed and the SD Zoo kiwi house was bulldozed. SD Zoo is supposedly building a nocturnal exhibit for aye-ayes in 2017.
